SIRIUS 3RT power contactors, size S3
Siemens SIRIUS 3RT power contactors, size S3
3-pole power contactors from 37 to 45 kW at 400 V, 70 mm wide.
Size S3 switches 80 to 95 A at AC-3. The contactors have either a conventional or an electronically controlled operating mechanism; the electronic mechanism picks up over a wide voltage range and markedly reduces holding power. Auxiliary contacts are removable, the main circuit is connected via box terminals.
Parent category: Siemens SIRIUS 3RT contactors.
